David,
I am not on Java 7, but I would be willing to give it a whirl.
$ java -fullversion
java full version "1.6.0_24-b24"
I am using the aries proxy that ships out-of-the-box...from the Karaf
startup.properties file:
org/apache/aries/proxy/org.apache.aries.proxy/0.3/org.apache.aries.proxy-0.3.jar=20
Regards,
Jason

Are you on java 7? I haven't followed this saga very closely but there were
some aries proxy changes needed for java 7.... which aries proxy bundle do you
have?

Hi all,
Just an update...
I just downloaded a fresh version of Karaf-2.2.8, did a checkout of
https://github.com/cschneider/Karaf-Tutorial, changed the
db/examplejpa/src/main/resources/OSGI-INF/blueprint/blueprint.xml file to have a
'default-activation="lazy"', then followed the bundle install instructions in
the readme.txt and this is the result:
karaf@root> person:add 'Christian Schneider' @schneider_chris
Error executing command: No transaction currently active
If I leave the 'default-activation="eager"', there is a java.lang.Verify
exception thrown:
Caused by: java.lang.VerifyError: (class:

At the very least, this tells me that I am not doing anything wrong from within
my codebase. Yet, I am still hung up on this issue. Suggestions?

Jason

David,
Yes....I deploy via a custom distribution, so all packages are set to start on
start-up. And I restarted the aries transaction bundle from the interactive
console.

You did install/start the aries transaction manager bundle?

Hi all,
I have been running into an exception lately and can't seem to remedy the problem. I am
getting a "javax.persistence.TransactionRequiredException: No transaction currently
active" exception. I am using Karaf v2.2.8, ActiveMQ 5.6.0, OpenJPA 2.1.1, and CXF
2.6.1. I followed the Apache Aries sample blog application, so there is a datasource
registered via blueprint...looks like this:

Here is the persistence.xml:

And finally, the blueprint.xml file to register JPA DAO services:
<?xml version="1.0" encoding="UTF-8"?>

</bean>
<service ref="accessControlDAOImpl"

...snip...
</blueprint>

The exception occurs whenever I try to do anything that is transaction related
(like persisting an entity). I have set the logging in Karaf to DEBUG and I
can't seem to find anything out of the ordinary. Anyone seen this before???
Suggested solutions? Suggestions for debugging further?
Regards,
Jason
